Figure 7

Mean EMG activity of the medial hamstrings (a) and lateral hamstrings (b) during the flexion and extension phases of the SLS task in the EO and EC conditions. The vertical bars represent the average activity on days 1 (dark bar) and 4 (white bar). The y axis represents muscle activity as a percent of maximum voluntary isometric contraction (MVIC). *Indicates significant difference from day 1 when conditions are combined. +Indicates significant difference from day 1 only during EO flexion. ^Indicates significant difference from EO only on day 1.
